I had fun on this today.
As you may probably know, there's something with the lua that needs to be fixed - sometimes players won't be able to be frozen, no matter how much you touch them. Also, if you are frozen, you can suicide or rejoin somehow (didn't really look into how it's done, but some guy was doing it in the server).
I'd add some doors on the roofs of the skyscrapers. Think it'd make them look less flat and give the runners more cover.
